Description

Technical Field

[0001] The utility model relates to the technical field of fiber yarn production, and further relates to a double-axis reciprocating annular wire laying machine and a sintering system. Background Art

[0002] As a kind of filament fiber, polycrystalline alumina continuous fiber needs to be laid out before entering the sintering furnace for degreasing and sintering, so that it can be continuously sintered in a certain shape to obtain qualified fiber products.

[0003] The currently used wire laying device is mainly composed of a reciprocating wire feeding mechanism and a conveyor belt. The reciprocating wire feeding mechanism moves back and forth in a certain translation direction. The conveyor belt is located below the reciprocating wire feeding mechanism. The conveyor belt is used to receive the fiber filaments dropped from the reciprocating wire feeding mechanism. The conveyor belt moves in a direction perpendicular to the movement of the reciprocating wire feeding mechanism to transport the fiber filaments to the sintering furnace.

[0004] When using this wire laying device, the fiber blank falls directly onto the conveyor belt after passing through the wire drawing accessories. The wire drawing accessories are controlled to move by the guide rail, and the fiber blank falls by its own gravity, forming a disordered state on the conveyor belt. There are large rings embedded in small rings, and the laid rings are uneven and irregular. The direction of the ring formation is also random in the counterclockwise and clockwise directions. In this way, the laid fiber blank has only one layer and the amount is relatively small. At the same time, due to the disordered state of the fiber blank laying, there are many bending positions of the fiber after sintering, which affects the uniformity of the fiber performance.

[0005] The conveyor belt is arranged in front of the lower end of the spinning tunnel. In the existing fiber laying method, one group of spinning tunnels corresponds to one sintering furnace, that is, one sintering furnace corresponds to one conveyor belt. The sintering amount of the fiber is low and the space utilization rate of the sintering furnace is not high, resulting in low output in actual production and inability to meet mass production needs.

[0006] For those skilled in the art, how to increase the unit sintering amount of fiber filament sintering is a technical problem that needs to be solved at present. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the double-axis reciprocating annular wire laying machine of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Combination Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a double-axis reciprocating annular wire laying machine, including a wire guiding mechanism 1, a moving wire connecting mechanism 2, a wire laying disk 3 and other structures. The wire guiding mechanism 1 includes a wire drawing accessory 11 and a wire guiding bracket 12, which are used to guide the fiber filaments. The wire drawing accessory 11 is positioned and installed on the wire guiding bracket 12. The wire drawing accessory 11 can adopt a wire laying wheel controlled by a servo motor, and guide the fiber filaments by rotating. The wire drawing accessory 11 is driven to rotate by the servo motor, so that the fiber filaments are guided at a certain speed, and the guiding speed of the fiber filaments can be adjusted accordingly.

[0030] The moving wire-connecting mechanism 2 includes a rotating spindle 21, an X-axis mover 22, a Y-axis mover 23 and a moving bracket 24. The axial direction of the rotating spindle 21 is vertically arranged. The rotating spindle 21 is rotatably mounted on the moving bracket 24.

The rotating spindle 21 is driven to rotate by a motor; the X-axis mover 22 is installed at the output end of the rotating spindle 21, and the rotating spindle 21 drives the X-axis mover 22 to rotate around the axis. The Y-axis mover 23 is installed at the output end of the X-axis mover 22, and the X-axis mover 22 is used to drive the Y-axis mover 23 to move along the X-axis direction.
